The present invention relates to a subscriber-based commercial ringback tone system using an intelligent network, and more particularly, to implement a system configuration for providing a sound source desired by a ringback tone service subscriber to a counterpart. It is not necessary to change the software of the existing exchange at the time of modifying the software or providing the sound source by modifying the commercial ringback tone (CBRT) system that adopts the intelligent network relay method and escapes from each modification method. The present invention relates to a ringback tone system using an intelligent network that can perform a unique function while minimizing the load on the system by processing a separate subscriber server.

In general, in a general telephone network, when a caller hears a telephone, the caller hears a dial tone, and when the caller presses the telephone number on the called party's side, a ring is ringed at the called party's terminal. You will hear.

In recent years, as the Internet and mobile technologies have made great strides, many attempts have been made to provide various contents to customers, and ringback tones can be set differently depending on the person receiving the call or to allow the called party to select a ring tone. (RBT) telecommunications services are starting to spotlight as a technology that can satisfy various needs of customers.

A representative example of ringback tone communication service is SK Telecom's first ring tone service in Korea, "Coloring", followed by LG Telecom's "Pilling" service, which was first developed by a Korean venture company. Starting from providing to Telecom, various patent applications such as systems, methods, and business models for such ringback tone communication services are being made.

FIG. 1 is a block diagram illustrating a conventional ring back tone system for providing such ring back tone communication service.

Referring to the block diagram shown in FIG. 1, the MSC (Mobile Switching Center), which is an exchange station having a wired or wireless telephone terminal 1, an originating exchange 3, and a destination exchange 4 as a whole, is referred to as MSC. (4), Home Location Register (HLR) (2), No. 7 and a structure in which the sound source providing device (IP) 6 are organically connected to each other by a wired / wireless network are disclosed.

More specifically referring to the configuration of Fig. 1, the MSC 4, which is a switching center, typically has a single MSC 4, as is known, that accommodates several base station controllers (BSCs) (not shown). , one BSC also each accommodates multiple (not shown), BTS (base station Transeceiver System, base stations), each BTS also comprehensive concept in Figure 1 the configuration for receiving multiple MS (mobile station) (not shown) It is shown as.

And, the HLR (Home Location Register, hereinafter referred to as "HLR") (3) is a device that is responsible for registering the home location in the mobile communication switching system, and queries the subscriber's information such as the location of the mobile subscriber , Registration, cancellation of additional services, and activation / deactivation of the mobile terminal.

In addition, when the sound source providing device (IP: Intelligent Peripheral) 6 receives a sound source providing request from the source exchanger 1 or the destination exchanger 2 in the MSC 4, the sound source providing device 6 is connected to the subscriber server. Requesting a code value for the corresponding sound source, and reproducing the sound source corresponding to the code value returned from the subscriber server and applying it to the calling party exchange 1 or the called party exchange 2;
